Is it a good idea to contextually name predefined functional interfaces?

I am currently working with Java 8 and using functional interfaces a lot. I often find myself writing code like this:

public interface MessageHandler extends Consumer<String> { }

Is this a good idea or an indicator of me abusing functional interfaces to make Java feel more like C#?

Edit: Maybe to expand a little:

public class MessageGenerator {

    public void registerMessageHandler(MessageHandler handler) { 
    // [...]

    public interface MessageHandler extends Consumer<String> { }
}
